<p>I recently learned about the ESP8266, a $5 chip that includes WiFi and is Arduino compatible. This means that all your DIY projects can now be done for a fraction of the price.</p>
<p>For this tutorial, I’ll walk through how to get going with ESP8266, get the temperature and humidity and report it to MQTT where Home Asssistant can pick it up.</p>

Home Assistant will keep track of historical values and allow you to integrate it into automation.

<p>It’s time for the August release and there is some serious good stuff this time. The core of Home Assistant has gone some serious clean up and a bump in test coverage thanks to <a href="https://github.com/balloob">@balloob</a>. If you’re a developer, make sure you read up on <a href="https://github.com/balloob/home-assistant/pull/251">the deprecation notices</a>. <a href="https://github.com/fabaff">@fabaff</a> did another great round of documentating all the various components.</p>
<p><strong>MQTT Support</strong><br />
<img src="/images/supported_brands/mqtt.png" style="border:none; box-shadow: none; float: right;" height="50" /> The big new addition in this release is the support for the MQTT protocol by <a href="https://github.com/fabaff">@fabaff</a> with some help from <a href="https://github.com/balloob">@balloob</a>. It will now be possible to integrate any IoT device that talks via MQTT. For the initial release we support connecting Home Assistant to a broker (no TLS yet). Components can now subscribe and publish to MQTT topics (<a href="https://github.com/balloob/home-assistant/blob/dev/config/custom_components/mqtt_example.py">see the example</a>) and also support for the automation component <a href="/components/automation/#mqtt-based-automation">has been added</a>. For more information, see <a href="/components/mqtt/">the MQTT component page</a>.</p>
